On Sunday, the pop star was spotted outside the Barkley Pet Hotel with her two sons, Sean Preston, 7, and Jayden James, 6, in Los Angeles.

And she was holding an adorable new dog.

While Britney's puppies are super cute ... her outfit was not. The "Scream & Shout" singer looked like she'd literally just rolled out of bed, wearing pajama shorts, a grey tank, sneakers and her hair in a messy bun.

Reports have surfaced that the former "X Factor" judge is in talks to sign a deal with Ceaser's Palace as a regular performer.

And while there have been rumors to the contrary, Vegas may not be out of the question for Spears ... at least according to her dog Hannah.

Yesterday, Britney re-tweeted a post from Hannah's Twitter feed (seriously) that said "Mommy, are dogs allowed to gamble in vegas? Gonna cash in all my bones for chips."

Britney's response: "I don't think so honey #VivaLasVegas : )"
